Install a roller bearing (9) in each planetary gear. Install a washer and a retaining ring (10) on both sides of the roller bearing.
Illustration 48 g00644532
Note: The large radius on the bearing inner race is facing the planetary carrier.
Heat four planetary gears (7) to a temperature of 135 °C (275 °F). Install the four planetary gears in the planetary carrier.

Install retaining rings (6) that hold the four planetary gears in the planetary carrier.
Use the following procedure in order to adjust the end play of the axle shaft:
Illustration 50 g00644634
Use Tooling (D) to measure the distance from the mating surface of the planetary carrier to the bottom of the counterbore for the thrust washer. Subtract the thickness of the bar stock (part of Tooling (D) ). Record this dimension as dimension (N) .
Illustration 51 g00644637
Push in on the axle shaft. Use Tooling (D) to measure the distance from the end of the axle shaft to the mating surface on the hub, as shown. Subtract the thickness of the bar stock (part of Tooling (D) ). Record this dimension as dimension (O) .
Subtract dimension (O) from dimension (N). Record this dimension as dimension (P). Subtract the desired end play of 0.45 0.15 mm (.018 .060 inch) from dimension (P) in order to determine the correct thickness of thrust washer (8) .

Select the appropriate thickness of thrust washer (8) that is determined in Step 26.a through Step 26.c. Install the thrust washer in the planetary carrier, as shown.

Note: Engaging the four planetary gears in planetary carrier (2) with ring gear (22) may be difficult during the installation of the planetary carrier.
Fasten a lifting sling to planetary carrier (2), as shown. Fasten an appropriate lifting device to the lifting sling. Place the planetary carrier in the planetary carrier's original location on the wheel studs in the hub. Use slots (M) as a reference in order to align the parts. Temporarily install four lug nuts. Install the lug nuts in 90 degree intervals. The planetary gears in the planetary carrier will not be engaged with ring gear (22) at this time. Slowly rotate the hub on the opposite side of the axle. Tighten each lug nut slightly. Continue to tighten each lug nut slightly. The force of the lug nuts against the planetary carrier and the slow rotation of the hub will cause the planetary gears in the planetary carrier to engage with the ring gear. After the planetary carrier is correctly installed, remove the four lug nuts.
